What to do after being bitten by mosquitoes or insects

After being bitten by insects, wash the affected area with clean water or soapy water to help remove insect saliva and bacteria, reducing the risk of infection. Next, apply an anti-allergy or anti-inflammatory ointment to the bite to relieve discomfort such as redness, swelling, and itching. If a severe allergic reaction occurs—such as difficulty breathing or widespread rash—seek immediate medical attention. Avoid scratching the bite to prevent worsening skin damage and potential infection. In daily life, preventive measures such as wearing long-sleeved clothing and long pants, using insect repellent, or burning mosquito coils can help reduce the likelihood of insect bites.
